I have extensive experience, primarily in hardware design I primarily work with Altium Designer, but I am also proficient in KiCAD, EAGLE, EasyEDA, and Allegro OrCAD. I also develop firmware, primarily for the following platforms: -ESP32, S2, S3, C3 y C6 -ESP8266 -STM32 -STM8 -AVR -ATSAM -RAK Wireless Modules -PIC, PIC32, dsPIC For clients who prefer it, I am familiar with various Arduino Cores to facilitate future code editing and small modifications that the client can handle themselves. I also have the capability to run multithreaded code on any of the aforementioned platforms. I also use IDEs such as: -STM32Cube -RUI (Rak User Interface) -IDF (Espressif) -Atmel Studio (ATSAM/ATMEGA)

This device is an 18-output PDM (Power Distribution Module), similar to the MoTeC PDM15 and PDM30, using mostly the same hardware, the same output MOSFETs, and similar protections to ensure performance comparable to those products, tailored to the client's needs. It is capable of switching outputs based on the programmed configuration, monitoring each output's current consumption. In case of overload, it cuts off power (similar to a relay with a fuse) and, if configured to do so, attempts a reconnection. It connects directly to the battery voltage terminal (operating from 8 to 36V) and can be controlled via dry contact inputs or through CAN BUS.
